Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545102, here are decompositions:
- 5 + 31545097 = 31545102
- 11 + 31545091 = 31545102
- 19 + 31545083 = 31545102
- 41 + 31545061 = 31545102
- 53 + 31545049 = 31545102
- 79 + 31545023 = 31545102
- 101 + 31545001 = 31545102
- 139 + 31544963 = 31545102
Showing the first eight; more decompositions exist.
